[0002] The quality of the fiber coating directly affects the mechanical strength, environmental resistance, and optical transmission efficiency of the fiber. Therefore, accurately measuring various parameters of the fiber coating, such as thickness, uniformity, and adhesion, is crucial to ensuring the high performance and reliability of fiber optic products.

[0003] Traditionally, devices used to measure fiber coatings often include fixed clamp designs that are directly mounted on the measuring equipment to hold the fiber for various tests. However, since fibers may have different sizes and specifications for different applications, fixed clamps cannot flexibly accommodate fibers of different sizes or types, which may lead to inaccurate measurements or damage to the fiber.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This embodiment of an apparatus for measuring fiber optic coating includes a base plate 1 and an adjustment assembly and a base 10 mounted on the base plate 1. A CCD camera 9 is mounted on the movable end of the adjustment assembly. A light source 11 and an oil tank 13 are mounted on the top of the base 10. A quartz crystal 12 is mounted on the side of the oil tank 13 opposite to the light source 11. One end of the CCD camera 9 is also opposite to the oil tank 13 and is on the same axis as the center of the quartz crystal 12. A rotating assembly is mounted on the top of the oil tank 13 and is connected to it. A clamping assembly is mounted on the shaft end of the rotating assembly.

[0022] In the above structure, the position of the CCD camera can be adjusted in the X and Y axes according to the measurement requirements by adjusting the component. The clamping component also facilitates the clamping and fixing of the optical fiber. At the same time, different clamping components can be replaced and fixed at the shaft end of the rotating component according to different optical fiber sizes. Therefore, it can be used for clamping and fixing various optical fibers. By using the rotating component, automatic rotation can be achieved to complete the measurement of the optical fiber, reducing manual intervention and speeding up the detection speed.

[0023] The adjustment assembly includes a platform 2 fixed to a base plate 1. An L-shaped plate is formed on the front of the platform 2, and an adjusting bolt 6 is threaded onto the L-shaped plate. A slide table 3 is slidably connected to the platform 2. One end of the adjusting bolt 6 is rotatably connected to the slide table 3. A lead screw device 7 is mounted on the top of the slide table 3, and a movable stage 8 is slidably connected and fixed to the nut end of the lead screw device 7. A CCD camera 9 is mounted on the movable stage 8. By rotating the adjusting bolt, which is threaded onto the L-shaped plate, the bolt moves forward and backward. Simultaneously, the adjustment bolt and the slide table rotate, thus pushing the slide table to move back and forth. The operation of the lead screw device also drives the movable stage to move left and right, thereby enabling adjustment of the X and Y axes of the CCD camera and improving measurement accuracy.

[0024] To further explain, a limiting plate 4 is fixed to the left side of the platform 2, and a waist hole is provided on the limiting plate 4. A limiting post 5 is threadedly connected to the left side of the slide table 3, and the limiting post 5 is located in the waist hole. When the slide table is moved and adjusted by adjusting the bolt, the limiting post will move in the waist hole, thereby limiting the slide table. When it moves to the appropriate position, the limiting post is tightened, thus also serving a positioning function.

[0025] The rotating assembly includes a support frame 15 fixed to and connected to the top of the oil tank 13. A hollow motor 16 is mounted on the support frame 15, and a hollow turntable 19 is mounted on the shaft end of the hollow motor 16. The clamping assembly is installed at the eccentric top of the hollow turntable 19. The optical fiber is clamped by the clamping assembly and passes sequentially through the hollow turntable, the hollow motor, the support frame, and extends into the oil tank. The hollow motor drives the hollow turntable to rotate, and with the cooperation of the clamping assembly, the optical fiber can be rotated to complete the automatic rotation measurement.

[0026] To further explain, a cone 25 extending into the oil tank 13 is installed at the bottom opening of the support frame 15, and the central hole of the cone 25 communicates with the opening of the support frame 15. The cone helps to guide and maintain the correct position of the optical fiber during rotation, further enhancing the accuracy of the measurement.

[0027] In addition, a cover plate 14 is installed on the top of the oil tank 13 to cover the hollow motor 16, thereby protecting the hollow motor 16.

[0028] Meanwhile, a photoelectric angle feedback plate 17 is fixed to the outer side of the cover plate 14. At least seven photoelectric sensors 18 are mounted on the surface of the photoelectric angle feedback plate 17. A trigger plate 26, which can pass through the concave surface of the photoelectric sensors 18, is installed at the bottom of the hollow turntable 19. Through the cooperation of multiple photoelectric sensors and the trigger plate, high-precision real-time monitoring of the rotation angle of the hollow turntable can be achieved. The photoelectric sensors and the trigger plate adopt a non-contact design, reducing mechanical wear and improving the reliability and lifespan of the system. The photoelectric angle feedback plate can provide stable and accurate angle data, providing a solid foundation for subsequent fiber optic coating measurements.

[0029] The clamping assembly includes a fixing seat 20 fixed at the top eccentric position of the hollow turntable 19. The fixing seat 20 is semi-circular, and two mounting blocks are formed on the bottom left side. The two mounting blocks are fixed to the hollow turntable 19 by screws. An optical fiber clamp 21 fixed by screws is slidably connected to one side of the fixing seat 20. The optical fiber clamp 21 has a slot on one side and a wire groove at the central axis. A clamping plate 22 that can cover the slot is hinged. A card block 23 that matches the slot is fixed on the side of the clamping plate 22 opposite to the optical fiber clamp 21. A pressure block 24 that is opposite to the wire groove is also fixed. The pressure block 24 is made of flexible material. A protrusion is formed on one side of the optical fiber clamp 21 above and below the clamping plate 22, and a V-shaped opening that communicates with the wire groove is formed on the protrusion. The design of the slot, block, pressure block and V-shaped opening achieves precise fixation of the optical fiber, avoiding displacement or damage of the optical fiber during measurement. The sliding connection and screw fixing method between the optical fiber clamp and the fixing base make the component easy to disassemble and replace, and can adapt to different sizes and types of optical fibers, improving the versatility of the device. At the same time, it reduces the pressure on the surface of the optical fiber while fixing it, preventing damage to the coating.

[0030] The working principle of the above embodiments is as follows:

[0031] By rotating the adjusting bolt and the lead screw, the slide and moving stage can be moved, thereby adjusting the CCD camera to a suitable measurement position. Then, the optical fiber is placed in the cable tray, guided by the V-shaped opening through the hollow turntable, hollow motor, support frame and cone, and extends into the oil tank. The clamping plate is closed to lock the card block into the card slot, and the pressure block presses the optical fiber to complete the fixation. When it is necessary to replace the clamping assembly, the screw on the fixing seat is unscrewed, so that the optical fiber clamp can be pulled out and replaced with an optical fiber clamp that is suitable for the optical fiber size. After the optical fiber is fixed, the hollow motor drives the hollow turntable to rotate, which in turn drives the fixing seat to rotate, and the optical fiber also rotates. The measurement is completed through the cooperation of the light source, quartz, oil tank and CCD camera.
